Pedology
What type of method is an organized way for scientist to gather in pursue scientific knowledge?
Scientific method
What are the three main components of the scientific method?
Hypothesizing ,observation ,experimentation
What is a way of explaining an object or event by using a set of facts?
Theory
If a theory has never been proven, false scientist, will call it what?
Law
What would prove the hypothesis false, this property of hypothesis is called what?
Falsifiability
What kind of variable is the factor that you can change to test your hypothesis ?
Independent variable
What type of variable is a factor that is observed to determine the results of the experiment?
Dependent variable
What kind of variable is the same in all groups?
Controlled variable
What kind of group is the group on which a test is performed?
Experimental group
What group in which the independent variable is absent? The group is not tested, but is used for a standard for comparison ?
Control group
What are any characteristics required to solve the problem?
Constraints
What is the minimum characteristics that a design must have to function at all?
Criteria
What is the study of reasoning that is essential for any scientist called?
Logic
What is a conclusion based on reasoning from evidence?
Inference
What kind of reasoning is reasoning from evidence to a more specific conclusion it is used to go by known facts. Discover a new fact that is their logical consequence?
Deductive reasoning
In deductive reasoning, a statement of fact is called?
Proposition
What kind of proposition is an if/then preposition?
Hypothetical proposition
What kind of reasoning is reasoning from specific evidence to a more general conclusion, the ultimate purpose of blank reasoning is to determine cause and effect?
Inductive reasoning
What is it called when an experiment repeat multiple times, keeping all factors of similar as possible ?
Repeatability
What means the others will reach the same conclusion by performing your experiment themselves under different conditions performing other experiments that test the same hypothesis?
Reproducibility
What is anything that provides a partial representation of something else?
Model
What kind of material is primarily derived from living organisms?
Organic material
What type of material is primary derive from nonliving matter?
Mineral material
What measures the pull of gravity on an object?
Weight
What measures how tightly packed matter is?
Density
What is the amount of space that matter takes up?
Volume
What measures the amount of matter in an object?
Mass
Humus is primarily a substance composed of what kind of particles?
Decomposition
What is it called when you reuse old materials?
Recycling
What are scientist called when they study soil?
Pedologist
What is the range of sand sleet clay in humans mixtures called?
Loam
What is a chart that provides standard names in descriptions of soil colors?
Munsell chart
What are the three most important mineral nutrients for plants primary plant food elements?
Nitrogen, phosphorus, potassium
What is a group of chemicals containing the element phosphorus bonds to oxygen and other elements?
Phosphates
What stimulates rapid growth of leaves, and stems and plants, a rich green color?
Nitrogen
what cycle helps nitrogen move from the air to the soil to be used by plants and then returned to the atmosphere to be used again?
nitrogen cycle
what is substance containing atoms of two or more elements bonded together?
compound
what is the element that is essential for cell division in growth and promotes plant Maturation?
Phosphorus
What is the use of science to solve practical problems?
Technology
In the engineering process, what are the minimum characteristic that I design must how to function at all?
Criteria
What are any characteristics required to solve the problem?
Constraints
What are the six steps in engineering design process?
One state a problem to be solved, to determine the criteria and constraints of the problem, three research and develop possible solutions to the problem, choose a design and make a detailed plan, five and test a prototype, six analyze the prototype and improve the design.
What is a model of a design or some part of a design that is used for testing?
Prototype
What is the primary function to contribute to the general health of the plant and improve disease resistance?
Potassium
What kind of bacteria can ammonia be converted to nitrate buy another kind of bacteria called ?
Nitrifying bacteria
What are at the root of plants that use oxygen from the air found in the blank and spaces of soil?
Pore spaces
What does impermeable mean?
Nonporous
Any collected water bellow The Soil surface is called what?
Groundwater
What is the depth that depends on two factors, the size and number of pores in the rocks and soil and the amount of recent rainfall?
Water table
What is nursing substances for plants?
Nutrients
What is a substance composed of only one type of atom?
Element
